DUST-ABSORBING COMPOUND.

Specificationof Letters Patent.

Patented July 7, 1908.

To all whom it may concern:

Be it known that I, FRANK D.'WoLronAm, residing in Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Dust- Absorbing Compounds, of which the followmg is a description.

My. invention has relation to improve ments in dust absorbing compounds.

The object of the invention is to produce an etlicient dust-absorbing compound especially adapted for use in preventing dust from rising during the operation of sweeping floors, or other surfaces, and also susceptible of use to great advantage in connection with the form of construction of dustless brush covered in the a lication for patent Serial No. 352,537, file lan. 16, 1907.

My improved compound consists of sawdust, larr coarse salt, and oil, and in preparing the compound I take a suitable quantity of sawdust or finely comminuted wood, prel orably red cedar, and treat it with lard so as to impart to it the required degree of consistency, about five per cent. of lard or tallow is mixed wit-h the sawdust to give it this rcquired consistency for absorbing and taking up dust. mixed with ten per cent. of coarse salt and with ten to fifteen per cent. of oil. If desired, formaldehyde, about two per cent. may be added, and also about one-half of one per cent. of an aromatic such as a mixture of oil of fennel, oil-of anise and terpinol. The compound, after the ingredients enumerated have been thoroughly commingled and mixed, is then ready for use.

The character of oil I prefer to use is a araffin distillate known as parallin oil. do not, however, wish to restrict myself to this particular character of oil, as common kerosene oil, or an other desirable oil, ma be employed, alt ough araliin oil has con found to give excee ingly satisfactory results as it not only adds certain antiseptic qualities to the compound, but it also, in connection with the salt and other ingredients, enables the co'mpoundto take up the dust most effectively.

The lard used in the compound not only imparts the proper amount of consistency, but it also assists in gathering up the dust, and in connection with the oil gives to the :pwdust the maximum, dust taking up quali- The sawdust so treated is then- The salt is used as an ingredient of the com ound for the urpose of increasing the weig t and compelling the sawdust to dropl by reason of the additional weight imparts thereto.

The formaldehyde when added acts as a germ killer, and the aromatic gives a pleasant odor to the compound.

I claim 1. The herein described dust absorbing compound, comprising sawdust or finely comminuted wood treated with and containing lard, and mixed with salt and oil.

.2. The herein described dust absorbing compound, comprising finely comminuted red cedar or red cedar sawdust treated with arid containing lard and mixed with salt and or 3.
